The displacement is precisely controlled by the drive mechanism 4, which can quickly adapt to the size of PCB boards of different specifications. The PCB board is non-contactly adsorbed and fixed by the vacuum adsorption plate 2, avoiding scratches or deformation of the board surface caused by traditional mechanical clamping. PCB boards with higher hardness can be adsorbed by the vacuum adsorption plate 2, and the positioning mechanism 3 then clamps and moves them, reducing the manual alignment process.

When the second rack 308 moves, it drives the second slider 309 to move within the second slide groove 102 and the third slide groove 201, thereby causing the second fixed plate 310 to move as well. When the multiple second clamping plates 312 at the end of the second fixed plate 310 abut against the PCB board, the multiple second clamping plates 312 can compress the second spring 311 according to the shape of the PCB board, so that the multiple second clamping plates 312 can adapt to the shape of the edge of the PCB board.
